Located at 20 boulevard des Filles du Calvaire in the 11th arrondissement, Dupain is a handcrafted bakery‑pastry shop open from Tuesday to Sunday (8 am to 8 pm weekdays, shorter weekend hours) and closed on Mondays. Founded in 2016 by Tanguy Lahaye alongside Julien Fouin and Ludovic Dardenay, Dupain quickly became a must‑visit on Paris’s gourmet map.

Everything here is organic: flours sourced from local mills (Moulins Bourgeois, Gilles Matignon), natural sourdough, and long 24‑hour fermentation for digestible, flavoursome, and long‑lasting bread. Among their signature items are the classic tradition baguette blending several types of organic flour (wheat, rye, spelt), priced under €1.20, and the famous "pain du cirque" – a seed‑packed loaf beloved even by the Bouglione Winter Circus.

Pastries are outstanding: caramel‑apple turnovers, brioche with natural pralines, seasonal fruit tarts, creamy flans, cheesecakes, Paris‑Brest choux… all made on-site daily with no colourants or preservatives and moderate sugar levels. The apple turnover and praline brioche are regularly described as “must‑tries.”

Inside, the minimalist sales space – dominated by pale wood and white – breaks with traditional bakery layouts: no bread wall, just a long linear display with loaves exhibited on wall shelves, styled like a culinary curiosity cabinet. A few tables at the back offer indoor or terrace seating, creating a calm, contemporary setting perfect after a stroll in the neighbourhood.

Dupain’s clientele includes locals, curious food lovers, nearby office workers grabbing sandwiches or quiches, and visitors seeking high‑quality organic products in a stylish environment. The atmosphere is young, urban, gourmet and value‑conscious.

Fun fact: Dupain’s baguette earned 3rd place in Paris’s baguette competition in 2017—a testament to their expertise. From its opening, the bakery embraced a gallery‑like aesthetic – a bold design choice that elevates the tasting experience.

Practical info: served by metro line 8 (Filles du Calvaire or Saint‑Sébastien‑Froissart), bus lines 20/96 nearby, Vélib bike stations close, and customer parking available.

In short, Dupain is the ideal spot for enjoying refined organic bread or creative pastries in a design‑driven, convivial atmosphere right in the heart of the Marais.
